Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men's bones, and of all uncleanness. Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.
Matthew 23:27-28 KJV
“Woe to you, [self-righteous] scribes and Pharisees, hypocrites! For you are like whitewashed tombs which look beautiful on the outside, but inside are full of dead men’s bones and everything unclean. So you, also, outwardly seem to be just and upright to men, but inwardly you are full of hypocrisy and lawlessness.
Matthew 23:27-28 AMP
This is not to shame you, but to make you aware of what the Bible says.
....for the children of this world are in their generation wiser than the children of light.
Luke 16:8 (b) KJV
....for the sons of this age [the non-believers] are shrewder in relation to their own kind [that is, to the ways of the secular world] than are the sons of light [the believers].
Luke 16:8 (b) AMP
To clarify: true holiness begins with the heart. Outward holiness is supposed to follow. Just because it begins with a holy heart, doesn't mean that the outward doesn't matter at all.
It just means that the heart is the first priority.
The way that we're obedient to the convictions of the Holy Ghost about the way we dress, is the same way that we'll be obedient to Him in our obedience in our daily lives.
Faith without works is a dead faith.
Christians purposely not displaying themselves to be lusted after, IS NOT LEGALISM!
